The last ingredient on the label is Ascorbic acid. You might have asked yourself, what is this mystery ingredient in my pesto?

We had the same question and we’ve talked to Roberto Panizza, aka the Pesto King, aka our pesto producer, A LOT about it.

Basically, ascorbic acid is what we commonly call Vitamin C. Seriously, go look at the ingredients in your vitamins, you will find ascorbic acid listed as an ingredient.

As Roberto explained, ascorbic acid in small quantities helps to preserve the vibrant green color of Genova DOP Basil. As the Food and Health department at University of Pennsylvania State says: “Ascorbic acid, also known as Vitamin C, is used as an anti-oxidant to keep fruit from darkening.”

When Robert says, small quantities he means it. Just 0.0028% of this pesto is ascorbic acid. Eat it and enjoy!
